Description

The present invention relates to hair care products in the form of hair sprays are applied, especially those that are not cause a bad smell and a bad smell Serten strengthening effect on the hairstyle with reduced Exercise drying time.

Hair sprays are widely used for the purpose that Strengthen hair and give support to the hairstyle. These hair sprays usually contain for consolidation as main components film-forming resins and also to improve grip an oil, lower alcohols such as ethanol or isopropyl alcohol as Solvent, a propellant, etc.

The solvents such as ethanol and the propellant evaporate and spread out in the air when spraying the hairspray. The can because of the bad and irritating Odor, which is perceived by the consumer, unpleasant cause pleasant sensations. However, since hair sprays are excellent are not suitable for strengthening the hair and the hairstyle hold, they are widely used by consumers. For now covering fragrances etc. are used to reduce odor sets to suppress the unpleasant smell, however their effects have so far been insufficient. Over the past few years also launched unscented hair sprays on the market, however could smell the raw materials and the lower alcohols are not effectively reduced thereby.  

JP-A 61-161214 describes a hairspray containing a certain organic silicone resin, a volatile silicone contains oil and a propellant; the job of this hairspray is however, the firm hold of the hairstyle, excellent shine as well as achieving straight hair; there is no hint there by suppressing the smell of the raw materials, esp especially the lower alcohols.

It is therefore the object of the present invention to have a hair care products to create a satisfactory consolidation of the hair without being irritating to the consumer or unpleasant smell when used.

The object is achieved in that the combined Ver use of a special volatile substance, a special one film-forming resin for hair fixation and one liquefied ten gas or propellant created a composition will not only have no annoying smell in the user dung, but also the drying time after the spray hen, which plays an important role in hair sprays, essential shortens, which immediately sets the hairstyle and lasts long, and the grip of the treated hair increases.

In particular, the present invention relates to a hair care agent, which is characterized in that it
(A) at least one or more volatile silicone oils of the general formula (I)

where m is a number from 0 to 5, and / or the general formula (II)

where n is a number from 3 to 7, and / or a volatile hydrocarbon with a boiling point of 0 to 40 ° C,
(B) at least one water-soluble high molecular compound, and
(C) contains at least one propellant.

The component (A) according to the invention, a volatile silicone oil, that represented by the above general formula (I) is preferably hexamethyldisiloxane (m = 0) or octa methyltrisiloxane (m = 1); the volatile silicone oil by the above general formula (II) is preferred Hexamethylcyclotrisiloxane (n = 3) or octamethylcyclotetra siloxane (n = 4).  

The other possible component of component (A), the cursed term hydrocarbon, is a hydrocarbon with a Boiling point from 0 to 40 ° C (preferably 5 to 40 ° C), and / or a linear or branched hydrocarbon with 4 to 6 Carbon atoms; Examples include neopentane (boiling point 9.5 ° C), isopentane (boiling point 27.9 ° C) and n-pentane (boiling point 36.1 ° C).

As component (A) of the present invention, at least used one of the listed possible connections; it can but also several of the volatile silicone oils mentioned and / or volatile hydrocarbons can be used.

The amount of the above-mentioned ingredient (A) in the hair care mean is preferably 0.01 or 0.1, especially 1 to 50 wt .-%, in particular 5, especially 10 to 40 wt .-%, calculated on the overall composition.

example 1

Hair cosmetic compositions no. 1 to 6 prepared according to Table 1 below and thereby uses the following procedure.

Thereafter, compositions No. 1-3 are compared to a commercially available spray (A) after smell, strengthening force and drying time according to that described below Procedure assessed.

  The results are summarized in Table 2.  

production method

First of all, the components, excluding propellant, are included other mixed or dissolved into a stock solution prepare, which is placed in a pressure vessel in the the propellant gas is filled in, resulting in the finished haircare metic composition results.

Odor assessment procedure

The intensity of the smell at the time of spraying unpleasant smell at the time of spraying, and the Inten quantity of the remaining fragrance after being sprayed on assessed on the basis of the following grading:

= very weak
○ = weak
○ ∼ ∆ = normal
∆ = moderate
× = strong

Procedure for assessing the Strength (degree of strengthening)

A strand of hair 18 cm long and 1.5 g in weight is included Moistened water, then ge around a rod of 2 cm in diameter wrapped and left to air dry. After the dry the rod is removed from the curly hair and that Sprayed on hair care products from a distance of 15 cm. To drying the hair in a thermo-hygrostati for 30 minutes device (at 20 ° C and 98% room humidity), where the extension of the curls is observed to the degree of To determine consolidation (in%). The degree of consolidation is in the case 35% in which no hair care product is applied to the hair is sprayed (untreated).

Procedure for assessing the drying time

Hair, which is placed on a replica of the human head (wig), is inserted and sprayed with hair care product from a distance of 15 cm; An organoleptic examination of the extent of drying is then carried out immediately at specified intervals.
Standard for the assessment of the drying time
